530 Coversion

[ZedHead]

The first number of the chain designates the chain pitch and represents the distance between each pin in eighths (1/8) of an inch.

630 chain is 3/4" pitch (or think of it as 6/8"), 530 chain is 5/8" pitch - so if you are not sure what size chain you have on your bike, just measure the pin-to-pin distance.

The second two numbers show the width of the roller section of the chain in eighth's of an inch with an assumed decimal point between the numbers. So 630 chain is 3/8" wide and 525 chain is 5/16" wide (2.5 eighths).

520 5/8 inch pitch, 1/4 inch wide
525 5/8 inch pitch, 5/16 inch wide
530 5/8 inch pitch, 3/8 inch wide
630 3/4 inch pitch, 3/8 inch wide

Please be sure you are measuring o ring chains. I think a non o-ring 630 chain may give more clearance than an 630 O-ring chain. The 530 would be most probably be an Rk530 o-ring.

That is a good point Garn .
Just measured my chains at the widest part ' pins ' , both O ring .
630 chain is 25.20mm
530 chain is 25.42mm
Clearly a slight difference due to the brands .

I'll be out there with me micrometer shortly............


.......... Hope I'm not eating 'humble pie'.

[Ginger Bear]

Okey dokey,

Just measured the 630 HD 'O' ring chain fitted to my toast rack....... 25.25mm across the rivets, then measured a 530 HD 'O' ring 25.05mm across the rivets, then measured a not so HD ')' ring chain..... 24.75mm across the rivets.

Obviously some manufacturing differences, but not enough to make any real difference, so for you Geoff, I'll say those three little words my wife just loves to hear.........................................................


I was wrong.

Ok Guyz looks like i need a 15t 5/8 offset front sprcket)180 rear tyre)was 3/8 but real close to the tyre ,gonna go with the 530 chain ,so whats the best fix to offset the rear sprocket,make some spacers up?would need to bring out 1/4 inch....Ta

What about using an old rear sprocket cut down ? you will need to have longer bolts ,or just space out with s/steel washers ?

This is a good read

I have some 6mm front sprocket spacers if that helps.

[PAULJAC47]

All good stuff thanks for offer of the spacers Zedhead,may need to take you up on that,link is good as its actually the bike i have now,was looking at the 5/8 offset but this brings chain real close to the frame,may be easier to get new 3/8 offset front standard rear sprocket and get slightly narrower rear tyre?

[Ginger Bear]

Paul, I might have a 5/8th 530 offset sprocket going spare, not sure if it's 17 or 18t.......

I'll have a look tomorrow for ya.

In my (and a few others) opinion, 19t is optimum, Piggy had a batch made up a while ago, you may find someone on the forum willing to part with one, otherwise its a special order from Talon at around £60-70

[PAULJAC47]

Ta Steve what do you sue to pack out the rear sprocket?

[Ginger Bear]

Paul,

Normal way forward is to machine down the sprocket carrier. I guess your's may have lost too much to suit the 3/8th offset sprocket.

Best way forward would be to source a new sprocket carrier & machine it to suit your new front sprocket. from what I understand, wheels are Suzuki, so finding a replacement should be easy & cheap. I also know PJ has a lathe that is well capable of doing the job.

Must go, the wife's on me case.

[Pigford]

Wheels are Bandit / GSXR, mid-late 1990's I think

[PAULJAC47]

Thanks Guyz!!

[Ginger Bear]

Just dug this out.... Kosman 5/8" offset 17t 530 with bearing nose.

Only place that the chain is a real problem is on the rearside of the lower footrest mount, nothing that can't be put right with a grinder.
